I installed kubuntu 13.10 beta 1 yesterday. Today, I installed bumblebee and I was tried to check my fps on video card. When I ran glxspheres an error command not found appeared. How can I install glxspheres?

I tried sudo apt-get install virtualgl but the package was not found.

  1. Download VirtualGL (.deb) from:
  2. Navigate to the folder containing the deb package and install it with:

    sudo dpkg -i VirtualGL_*.deb

  3. Run glxspheres:

    cd /opt/VirtualGL/bin/

The website address should now be: pick the newest stable version, and then choose the deb release. – BenB Jan 14 '14 at 0:36

In 13.04 and older it is provided by mesa-utils package:

$ sudo apt-get install mesa-utils

Also in older releases virtualgl is not in the default repositories. If this is still the case you can use Bumblebee PPA to get it.

I have added this PPA but now bash sad virtualgl is the latest version and glxspheres not found :( – set4812 Sep 11 '13 at 12:39
So, even after doing that apt-get install you still get that error with glxspheres? – Salem Sep 11 '13 at 12:41
Joren method help me – set4812 Sep 11 '13 at 12:43
@Salem he's using Ubuntu+1, or more accurately Ubuntu 13.10 Saucy Salamander, hence, normal methods could not work. – Braiam Sep 11 '13 at 12:54
This is the most native and easiest one. Only sphere won't be there but glxgears can do the job or it's friends. – Ikon Dec 20 '13 at 10:13
